  1. 1. Development of an on-board charger model for real time simulation

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Neil Wagle; [2022]
    Keywords : On board charger OBC ; Hardware in loop HIL ; Precharge; Power factor correction; Electric vehicle EV charging; Vehicle to grid V2G service; Omboardladdare OBC ; Hardware in loop HIL ; Precharge; Effektfaktorkorrigering; Laddning av elfordon; Tjänst för fordon till elnät;

    Abstract : Electrification of vehicles is now one of the top priorities of automotive manufacturers in orderto comply with the sustainability goals and standards set by the United Nations. One of thedisadvantages faced by electric vehicles is a longer time required for charging the vehicles ascompared to refuelling a conventional vehicle. READ MORE

  3. 2. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Author : Louise Olausson; [2022]
    Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

  4. 3. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Henrik Johansson; [2022]
    Keywords : Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

    Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE

  5. 4. Parameter Study of Arc Squeezing DC Breaker : The impact of the geometry on counter force, pressure, and arc voltage

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johanna Olsson; [2022]
    Keywords : Arc squeezing; DC breaker; Polymer ablation; Pressure measurement; Ljusbågssläckning; DC brytare; Polymerablation; Tryckmätning;

    Abstract : The sustainable future in our already electrified world includes solar power generation, battery storage, and electric vehicles all which requires DC systems. DC breakers play a key role in operation and protection within the DC system. READ MORE

  6. 5. Condition Based Reliability Evaluation and Maintenance Strategy for Battery Energy Storage System

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Novalie Hou; [2022]
    Keywords : Battery Energy Storage System; Reliability Evaluation; Maintenance Strategy; Batterienergilagringssystem; Tillförlitlighets Evaluering; Underhållsstrategi;

    Abstract : The electrical grid balances production capacity and demand in real-time. With an increased demand for renewable energy sources, challenges such as stability of the grid, the balance between generation and demand, and power quality occur. READ MORE
